Show ContentsCroly History, Family Crest & Coats of Arms

Irish names tend to vary widely in their spelling and overall form. The original Gaelic form of the name Croly is "O Cruadhlaoich." This is derived from the words "cruadh," which means "hard," and "laoch," which means "hero." 1

Early Origins of the Croly family

The surname Croly was first found in Moylurg, in the County Roscommon, where they started as a branch of the MacDermots. It is from Teige, a Prince of Moylurg, down to Cruadhlaoch that the line of descent for the Crowleys begins. A junior branch of the Crowley family also emerged and moved to the area of Dunmanway, in the west of County Cork. They eventually became a distinct sept with their chief at Kilshallow, thriving while their parent family gradually withered. The majority of the Crowley family came to be found in the county of Cork, with three-quarters of the family being born there in modern times. 2

Migration of the Croly family

In the 19th century, thousands of Irish left their English-occupied homeland for North America. Like most new world settlers, the Irish initially settled on the eastern shores of the continent but began to move westward with the promise of owning land. The height of this Irish migration came during the Great Potato Famine of the late 1840s. With apparently nothing to lose, Irish people left on ships bound for North America and Australia. Unfortunately a great many of these passengers lost their lives - the only thing many had left - to disease, starvation, and accidents during the long and dangerous journey. Those who did safely arrive in "the land of opportunities" were often used for the hard labor of building railroads, coal mines, bridges, and canals. The Irish were critical to the quick development of the infrastructure of the United States and Canada. Passenger and immigration lists indicate that members of the Croly family came to North America quite early: Alice Crowley settled in Jamaica in 1661; Alice, Bridget, Catharine, Cornelius, Dan, Eliza, Harry, James, Johanna, Judith, Mary, Michael, Pat, Timothy, and William Crowley, all settled in Boston Massachusetts in 1849.
